ATTACHMENT FOR LIFE-BOATS.

To all whom, it may concern.

Be it known that I, ALBIN E. WICKMAN, a citizen of Sweden, residing at Peoria, in the county of Peoria have invented certain new and useful Improvements in Attachments for Life-Boats, of which the following is a specification.

This invention relates to improvements in attachments for life boats. Its object is to produce such an attachment that will prevent the sinking of the boat in heavy seas.

Another object is the provision of means for becalming a heavy sea in the'immediate vicinity of the boat.

Other objects are cheapness of manufacture and efiiciency.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully. described in the following specification, pointed out in the claims and illustrated -in the accompanyin drawing which forms a part of said specification and in which-'- Figure 1 is a plan of a life-boat or yawl embodying my improvement. Fig. 2 is a side elevation with part of the attachment shown in section. Fig. 3 is a vertical section taken on line 33 of Fig. 1. Fig. 4 is a detail showing a cross section of the exhaust pipe and means of securing the same to the boat.

Like reference characters indicate corresponding parts throughout the several views.

2 is the hull of the boat having an upper ed e 3 and just below this edge on the out sife of the hull is located my improved attachment. A pair of upper and lower longitudinal cleats 4: and 5 respectively extend approximately the length of the boat from one end to the other and between them support a hollow trough-like member 6 that is U-shaped in cross section having the opening dlsposed against the side of the boat. Fitting snugly within the cavity of this member is a hollow tank 7 which is circular in cross section and divided longitudinally into an upper and lower compartment by means of a resilient partition 8 made of rubber or similar material. The upper compartment is designed as a receptacle for petroleum and thelower "for compressed air, the resilient partition 8 coming'between the two. Upon the base of the U-shaped mem- Specification of Letters Patent.

her 6 upper and lower cleats 9 and 10 respectively are secured and between these cleats is carried a guard 11 for preventing exterior contact with the attachment proper or with the tank thereof.

A hollow exhaust pipe 12 disposed beneath the guard 11 is suitably secured thereto and extends lengthwise of the boat a short distance above the water line. Upon the upper edge of the side of the boatis located a faucet 13 connected by a pipe 14: with the oil tank and from the opposite end of this faucet another pipe 15, as shown in Fig. 3, makes connection with the exhaust pipe 12. A suitable opening B is provided in the oil tank for filling the same and the compressed air chamber can, of course, be filled in any desired manner. The compressed air carried in the tank naturally gives the'boat an added degree of buoyancy and at the same time furnishes sufficient power to cause the evacuation of the oil in the oil tank when the faucet is opened as the resilient partition 8 transmits the energy of the air to the oil. The oil is forced from its tank up through the pipe 14 and through the faucet out through the pipe 15 into the exhaust pipe 12 that empties it into the sea thus becalming the troubled waters in the vicinity of the little craft.

What I claim is 7 1. The combination with ayawl or boat of, a longitudinally extending tank secured to the hull thereof, a resilient partition within said tank for dividing the same into upper and lower compartments, the upper compartment being adapted to contain oil, a faucet disposed upon the upper side of the yawl having connection with the upper tank compartment and means within the lower tank compartment for ejecting the contents of the oil compartment through the said faucet.

2. The combination with a yawl or boat of, a longitudinally extending tank secured to the hull thereof, a resilient partition withinsaid tank for dividing the same into adjoining compartments, one of said compartments being adapted to retain oil andthe other gas and a faucet arranged upon the top of one side of the boat and having connection with the oil compartment.

3. The combination with a yawl or boat of, a longitudinally extending tank secured within said tank for dividing the same intei to the hull thereof, a resilient partition oil and gas compartments, a hollow U- as my own I have hereto aflixed my signashaped member encircling said tank, a tank ture in the presence of two subscrlbing wit- 7 exhaust pipe.
